               SPSS INC. PRICES $125 MILLION PRIVATE PLACEMENT OF
                  2.50% CONVERTIBLE SUBORDINATED NOTES DUE 2012

CHICAGO, Ill., March 13, 2007 -- SPSS Inc. (NASDAQ: SPSS) today announced the
pricing of its offering of $125 million aggregate principal amount of 2.50%
Convertible Subordinated Notes due 2012 to qualified institutional buyers
pursuant to Rule 144A under the Securities Act of 1933, as amended (the
"Securities Act"). The sale of the notes is expected to close on March 19, 2007,
subject to satisfaction of customary closing conditions. SPSS also granted the
initial purchaser of the notes a 30-day option to purchase up to an additional
$25 million aggregate principal amount of notes, solely to cover
over-allotments.

The notes will pay interest semiannually at a rate of 2.50% per year and will be
subordinated to all present and future senior indebtedness of the Company. The
notes will be convertible, subject to certain conditions. Unless SPSS has made
an irrevocable election to physically settle, upon conversion of a note, a
holder will receive cash in an amount equal to the lesser of $1,000 and the
conversion value and, if the conversion value is greater than $1,000, payment of
the excess value, at the Company's option, in the form of cash, shares of
Company common stock or a combination of cash and common stock. The initial
conversion rate is 21.3105 shares of common stock per $1,000 principal amount of
the notes (which is equivalent to an initial conversion price of approximately
$46.93 per share), subject to adjustment upon the occurrence of certain events.
This represents a conversion premium of approximately 42.5% relative to the last
quoted sale price of the Company's common stock on the Nasdaq Global Select
Market on March 13, 2007.

As previously announced, SPSS intends to use $50 million of the net proceeds
from the offering to purchase approximately 1.5 million shares of its
outstanding common stock at $32.93 per share in connection with this offering.
SPSS intends to use the remaining proceeds of this offering for general
corporate purposes, including potential acquisitions.

This press release does not constitute an offer to sell or the solicitation of
an offer to buy any of these securities and shall not constitute an offer,
solicitation or sale in any jurisdiction in which such offer, solicitation or
sale is unlawful.

The notes and the shares of common stock issuable upon conversion of the notes
have not been registered under the Securities Act or any state securities laws
and, unless so registered, may not be offered or sold in the United States
except pursuant to an exemption from the registration requirements of the
Securities Act and applicable state securities laws.
